Description

Technical Field

[0001] This utility model belongs to the technical field of linear motor structure, specifically a heat dissipation structure for a linear motor mover assembly. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without the need for an intermediate conversion mechanism. It has advantages such as simple structure, small size, and high precision. However, due to its compact size, it generates a lot of heat inside during operation, which is difficult to dissipate. Overheating of the motor will reduce its performance. Therefore, existing technologies all set up corresponding heat dissipation structures for linear motors, such as the published technical document "CN221380651U Open Heat Dissipation Structure for Linear Motor". Cooling gas acts directly on the surface of the heated mover of the linear motor through the cooling system, reducing the temperature of the mover of the linear motor.

[0003] However, the heat generated by a linear motor is not on the surface but inside, so the above-mentioned technical solutions cannot effectively remove the internal heat, resulting in poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for a linear motor actuator assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat dissipation structure for a linear motor mover assembly includes a mover body, in which a plurality of metal tubes are inserted. The two ends of the plurality of metal tubes extend from the end face of the mover body to form an air inlet and an air outlet, respectively, and airflow is continuously introduced into the plurality of metal tubes.

[0007] In a further technical solution, the moving body includes a mounting frame, on which coil group one and coil group two are respectively mounted on both sides, and several metal tubes are respectively disposed inside coil group one and coil group two.

[0008] In a further technical solution, coil group three and coil group four are also installed on both sides of the mounting frame. Coil group three and coil group four are located inside coil group one and coil group two, respectively. Several metal tubes are distributed between winding group one and winding group three, inside winding group three, between winding group two and winding group four, and inside winding group four.

[0009] In a further technical solution, the moving body includes a mounting frame, and several fixing parts for fixing the winding group are respectively provided on both sides of the mounting frame. A metal tube is provided for each winding group, and the metal tube meanders around each fixing part.

[0010] A further technical solution also includes an outer cover, which is connected to a mounting bracket to encapsulate the coil assembly.

[0011] The beneficial effects of this utility model are:

[0012] This invention employs several metal tubes inserted deep into the moving part of the body, distributing them around the heat source and placing them very close to it. This allows the heat to be absorbed quickly when the heat is dissipated, greatly improving the heat dissipation effect and preventing heat accumulation. It also reduces heat transfer between adjacent components, thus reducing the impact of mutual interference.

[0013] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please refer to Figure 1-3 ;

[0020] The heat dissipation structure described in this utility model aims to dissipate heat inside the mover assembly of a linear motor, further improving the heat dissipation effect. First, it is necessary to introduce the components of a linear motor, which mainly consists of a stator assembly and a mover assembly. The mover assembly usually contains a coil, while the stator assembly contains a permanent magnet. Normally, the stator assembly is fixed, while the mover assembly is connected to the moving part. However, this method causes a dragging motion on the cable during the movement of the mover assembly, which can easily lead to cable fatigue. Therefore, in the prior art, the mover assembly can be fixed, while the stator assembly is connected to the moving part, achieving the same effect without dragging the cable during movement.

[0021] Regardless of which method is used, the main heat generation comes from the process of current passing through the wire, and a large amount of heat will accumulate inside. Therefore, in this embodiment, a number of metal tubes 2 are inserted into the moving body 1. The upper end face of the moving body 1 is provided with a mounting plate for installing other components. The two ends of the metal tubes 2 extend from the end face of the moving body 1 to form an air inlet 21 and an air outlet 22, respectively. In order to avoid blocking the air outlet 22 and the air inlet 21, the mounting plate can be made too high for the part connected to the external components to form a clearance. Of course, these can be solved by common technical means or existing technology. In addition, the metal tubes used in this embodiment should have good thermal conductivity, but should not be magnetic, such as copper and aluminum.

[0022] During operation, the heat generated inside the moving part assembly is radiated to the metal tube 2 through heat transfer. At this time, a continuous airflow flows into the metal tube 2 from the air inlet 21 and flows out from the air outlet 22 of the metal tube 2. The high-speed airflow carries away the heat of the metal tube 2 when it passes through the metal tube 2, keeping the metal tube 2 at a low temperature so that it can continuously absorb the heat inside the moving part body 1. Preferably, if the low-temperature airflow is introduced, the metal tube 2 can be kept at an even lower temperature, resulting in better heat dissipation.

[0023] This invention employs several metal tubes 2 inserted deep into the moving body 1, distributing the metal tubes 2 around the heat source and placing them very close to it. When dissipating heat, the metal tubes 2 can absorb the heat in a short time, greatly improving the heat dissipation effect and avoiding heat accumulation. This reduces heat transfer between adjacent components and also reduces the impact of mutual interference.

[0024] Preferably, since there are several air inlets 21 and air outlets 22, two flow splitting components can be provided. The flow splitting components have a main interface and several sub-interfaces. The several sub-interfaces are connected to the air inlets 21. Airflow is input from the main interface and then split into each air inlet 21 by the several sub-interfaces.

[0025] Alternatively, the aforementioned moving component can be used for fixed installation, while the stator component is connected to the moving part. There is no dragging action during the movement, which can avoid pulling on the trachea.

[0026] Further explanation of the mover assembly: the mover body 1 includes a mounting frame 11, on which coil group one 12 and coil group two 13 are respectively mounted on both sides. Several metal tubes 2 are respectively arranged inside coil group one 12 and coil group two 13. Each coil group is composed of several parts. If the volume of a single part is large, one metal tube 2 can correspond to one part. If the volume of a single part is small, one metal tube 2 can correspond to multiple parts.

[0027] It should be noted that the mounting bracket 111 consists of a bracket 111 and stacked silicon steel sheets 112, and the coil assembly is wound on the silicon steel sheets 112.

[0028] In addition, based on this embodiment, the coil groups on both sides are separated by several metal tubes 2 to avoid mutual interference.

[0029] Furthermore, multiple coil groups may be provided as needed. Specifically, coil group three 14 and coil group four 15 are installed on both sides of the mounting bracket 11. Coil group three 14 and coil group four 15 are located inside coil group one 12 and coil group two 13, respectively. Several metal tubes 2 are distributed between winding group one and winding group three, inside winding group three, between winding group two and winding group four, and inside winding group four. The metal tubes 2 are respectively set between these coil groups to separate them from each other, and also to bring the metal tubes 2 closer to the heat source.

[0030] In another embodiment, the mover body 1 includes a mounting frame 11, and a plurality of fixing parts 16 for fixing the winding group are respectively provided on both sides of the mounting frame 11. A metal tube 2 is provided for each winding group, and the metal tube 2 is meandering around each fixing part 16. This design can minimize the use of metal tube 2 and make the metal tube 2 correspond to each part of the coil group, making the design more reasonable.

[0031] Based on all the above embodiments, an outer cover 17 is also included, which is connected to the mounting bracket 11 and is used to encapsulate the coil assembly.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
